We assess the quantitative impact of two reforms to corporation tax, which would eliminate the differential treatment of debt and equity: the allowance for corporate equity (ACE) and the comprehensive business income tax (CBIT). We explore the impact of these reforms on various decision margins,...

This paper explores the economic consequences of proposed EU reforms for a common consolidated corporate tax base. The reforms replace separate accounting with formula apportionment as a way to allocate corporate tax bases across countries. To assess the economic implications, we use a numerical...

This paper investigates whether OECD countries compete with each other over corporation taxes, and whether such competition can explain the fall in statutory tax rates in the 1980s and 1990s. We develop a model in which multinational firms choose their capital stock in response to an effective...

We examine whether discretionary government grants influence where domestic and multinational firms locate new plants, and how the presence of agglomeration externalities interacts with these policy instruments. We find that a region's existing industrial structure has an effect on the location...

This paper provides a simple but general theoretical framework for analyzing simultaneous vertical and horizontal competition in excise taxes, which includes several previous contributions as special cases. It allows for both elastic individual demand for the taxed good, and cross-border...

We investigate the geographic concentration and agglomeration of production activity in the UK at the four-digit industry level using a variety of measures. We relate these to comparable patterns in the US and France and find several similarities. We find that conditioning on industrial...

This paper explores the optimal international tax policy of a small open economy with inbound and outbound flows of both portfolio and direct investment. Only three independent conditions determine the optimal rates of six taxes, implying that there are no unique values of optimal tax rates. For...
